- Abstract:
- The research objective of this project is to accurately, densely and remotely measure the state of the soil using plants as in situ chemical laboratories. The sap of these "interrogator plants" will be analyzed by implanted bioelectronic sensors and remotely communicated by low-power radio interrogation. This approach will avoid the complexity of sensing the soil directly by instead detecting the chemical response of vascular fluids to chemical and biological changes of the soil around the roots. These fluids, which are transported by the woody xylem tissues, are under negative pressure and thus typically difficult to access. The project will thus investigate a number of regeneration techniques for surgically implanted, small sensors such that these sensors become grafted into the xylem tissue, much like fruit trees are currently grafted. The entire small sensor including implanted electronics and regenerative coating will be screen-printed for very low cost. Screen printing recipes and other enabling techniques will be shared with the public through the Open Science Framework. Public use of these results will be further fostered by funded kits distributed to teams through the international BioMaker and OpenPlant programs.
